1<?php
Simple class for loading configuration files, and saving the data back when necessary. All config files are php files, each with a return statement followed by the configuration (array). All of them should be in configs/ folder. They should have the same name as the file that uses them. I.e. a configuration for libs/Article.php should also be in  configs/Article.php. Naming is just a convention, though. (2009.02.10 18:11)[update][delete]

Writes configuration back to the file, or deletes the file if the configuration is NULL. (2009.02.10 18:18)[update][delete]
